Equator (Uriah Heep album)

Equator was the sixteenth album released by British rock band Uriah Heep, released in 1985. It marked the studio return of bassist Trevor Bolder, who had rejoined the band for the Head First tour. The band also had a new record label, Portrait Records, a subsidiary of CBS.

The tour programme would be Heep's last in the UK until the Wake the Sleeper tour, which began in 2008.

When the Heep back catalogue was issued on CD in the early 1990s by Castle and then remastered, with bonus tracks, in the mid-to-late 1990s by Essential, Equator was conspicuous by its absence. This was because Sony/CBS wanted what was considered an extortionate sum for the rights. The album ultimately had a CD release in 1999, with no bonus material whatsoever. When the Essential remasters were expanded and reissued in the early 2000s by Sanctuary, Equator had to be passed over once again. However, in 2010, the album finally saw a release in expanded and remastered format, in time for its 25th Anniversary, thus finally ending Sanctuary's remaster-series.

Equator (Randy Stonehill album)

Equator is an album by Randy Stonehill, released in 1983, on Myrrh Records.

An equator is the intersection of the surface of a rotating sphere with the plane that is perpendicular to the sphere's axis of rotation and midway between its poles. The equator usually refers to the Earth's equator: an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is about long; some 78.7% lies across water and 21.3% over land. Other planets and astronomical bodies have equators similarly defined.
